Calexg, i have all my music on my phone sd card. With that, i can create playlists and change my tunes if the ones i have now are played out. I have an android phone so it's very easy that way. I have no experience with sites that store purchased music, however, as all my music comes from cds and youtube. Real player allows you to download youtube music videos and then convert to mp3 format. If i find an answer to your question, i will post it here for you or to an email if you provide it.
